While studies reveal that meal replacement shakes are indeed healthy, there are certain best practices to consume them that we must adhere to.

Let us find out more about the benefits of meal replacement shakes, the variety of such shakes available to drink, and just how nutritionally balanced they are.

Are Meal Replacements Good For You? What Experts Say…

Health benefits of Meal Replacement Shakes

Are meal replacement shakes healthy?

This is the question we started with.

Well, research shows that diet plans or changes in diet that include meal replacement shakes aided in higher weight loss, stabilized levels of C-reactive protein (CRP, which identifies and regulates inflammation and infection), and led to an overall improvement in health.

Here is a more elaborate understanding of how meal replacement shakes offer such benefits…

1) Support weight loss

Since these shakes can be considered a complete meal, people looking to lose weight can go the protein shake way to get the best results.

Since these are filling in nature, consuming these shakes reduces cravings for unnecessary consumption of processed foods and thus aids in weight loss.

Plus, many replacement shakes contain essential nutrients the body requires, such as high protein and adequate amounts of vitamins and minerals.

2) Better substitute than fast food

Meal replacement shakes are a much healthier alternative if you’re on the go and want to grab a quick meal than an easily available burger, pizza, or fried chicken meal.

Not only do they carry fewer calories, but they are also much more nutritionally balanced than fast food options. They will not give you digestion issues or constipation like some fast food items tend to do.

2) High in protein and fiber

We’ve all heard about the importance of getting enough protein in our diets.

Foods containing high protein content are recommended for most, especially those who lead an active lifestyle.

This is because protein fills the stomach up longer than our favorite carbs and fats, and protein shakes can do that for you.

Plus, they’re high in fiber and straightforward to digest and support precise bowel movements.

2) Easy and fun DIY

While store-bought protein shakes, mixes and powders are easy enough to procure and use, especially if you don’t have much time, you can also always prep your own at home.

You can customize the ingredients to suit your taste and preferences; use almond milk, soy milk, nuts, bananas, berries, and dark chocolate- go wild; it’s your call!

This way, you can avoid the extra sugar and often artificial flavors that go into commercial shakes.

There is also a good variety of shakes you can buy or make depending on your purpose of consumption – from keto shakes for weight loss to whey-based shakes for weight gain, green smoothie shakes for detox, and chocolate or caramel for that sweet kick; there’s something for everyone here.

Pluses and Minuses

Although meal replacement shakes provide a complete meal, they also have drawbacks.

If you’re thinking of replacing meals with protein shakes, you may want to keep these points in mind-

1) It may contain artificial flavors

This is particularly true for store-bought replacement shake mixes and powders – often, to make the shake more palatable and just a tad bit delicious, companies tend to add a good number of artificial flavors, from cocoa to matcha to vanilla, to these mixes.

In addition, many commercial shakes are likely to contain added sugar, which is a no-no if you’re avoiding processed foods and using meal replacement mixes to stay healthy.

So, when purchasing replacement shakes or mixes/powders, take a moment to look at the composition and assess whether this is truly what you desire.

2) Contain fewer calories

While one of the primary purposes of vegan replacement shakes is to fill the stomach without adding too much calorie consumption, this can disadvantage certain people.

On average, meal replacement shakes contain between 150 to 200 calories, so even if you take one for each meal, it would add up to not more than 1000 calories, which is not nearly enough to sustain the body.

Science suggests that an average woman’s calorie intake should lie within a range of 1600 to 2400 calories daily, while men would require between 2000 to 3000.

So, when considering meal replacement, make sure you supplement these shakes with healthy snacks and supporting foods that contain all the nutrients you need, and the shake may not be able to offer.


In conclusion, we derive that meal replacement shakes are a healthy way to replace meals, lose weight, detoxify your system, and just try to eat better.

However, this comes with the important caveat that you remember to balance these shakes with healthy balanced foods and don’t end up replacing meals regularly.

Even the best meal replacement shakes cannot ultimately substitute fully for natural solid food.
